Distributed Fault-Tolerant Control of Large-Scale Systems: An Active Fault Diagnosis Approach

摘要: The paper proposes a methodology to effectively address the increasingly important problem of distributed fault-tolerant control for large-scale interconnected systems. approach dealt with combines, in holistic way, fault detection and isolation algorithm specific tube-based model predictive scheme. A strategy is illustrated guarantee overall stability constraint satisfaction even after occurrence fault. In particular, each subsystem controlled monitored by local unit. diagnosis component consists passive set-based an active one, yielding fault-isolability subject input state constraints. module–thanks modification inputs–allows isolate that has occurred, avoiding usual drawback controllers possibly hide effect faults. Active Fault Isolation method used as decision support tool detection. design allows possible disconnection faulty subsystems or reconfiguration isolation. Simulation results on well-known power network benchmark show effectiveness proposed methodology.
